Description
Technical field
It the utility model is related to a kind of coal excavation apparatus, and in particular to a kind of flitting for ultra-thin coal seam.
Background technology
Coal is the main body energy in China, and coal industry is the important foundation production of relation energy security and lifelines of the national economy
Industry.Coal seam of the thickness less than 1.3m is incorporated in China into belongs to ultra-thin coal seam for girdle, coal seam of the thickness less than 0.8m.Study of Thin
And ultra-thin coal seam high efficient mining technology has important practical significance.China's girdle resource distribution is extensive, below 1.3m coal seams
Recoverable reserves accounts for the 20% of whole recoverable reserves.It is very big in some provinces, area's girdle reserves proportion, as Sichuan Province accounts for 60%,
Shandong Province accounts for 54%, and Heilongjiang Province accounts for 51%, and Guizhou Province accounts for 37%.Particularly accounted for only in southern area, some province girdles
More than 50%, and girdle distribution is wide, and ature of coal is good.It is but thin compared with middle thick and high seam due to its working seam thickness of thin
There is working under hard conditions, equipment movement is difficult for coal seam mechanical mining, the geological structure such as Coal Seam Thickness Change, tomography, to thin
Coal seam equipment production performance influence is big, and input-output ratio is high, economic benefit is not so good as the specific questions such as thick and medium-thickness seam, makes
It is relatively slow into girdle mechanical mining technology development speed.
In addition, to some thin, high seams and the colliery deposited, because thin seam mining speed is slow, make the middle thickness of its underpart
Coal seam cannot exploit in time for a long time, be taken over so that influenceing the normal of working face, and some can only just be forced to lose some bog-head coals
Layer resource.With in large quantities of collieries, the resource exploitation of high seam it is relatively more so that resource is fewer and fewer, so girdle is opened
Adopt and be included in schedule.Therefore, the low seam mining machinery for being adapted to the actual national conditions in China is developed, to adapt to different coal bed textures, is carried
The operating efficiency that high girdle is mined is the task of top priority.Initial stage is generally preferentially exploited medium-thickness seam in past, each mining area in operation,
Less than 1.3 meters of coal seam is all abandoned, and wastes a large amount of precious resources, shortens the viability of mine, constrains whole coal
The coordinated development of charcoal industry.Coal is non-renewable resources, and many collieries are with the continuous extension of the exploitation time limit, medium-thickness seam money
Source is close to exhaustion, for the Yanchang Area length of service, it has to start back production thin layer coal.In this case, in order to treasure
Existing coal resources, coal resources are liberated by every possible means, improve coal recovery rate to greatest extent.
China's low seam mining machinery passes through the development of more than 40 years, and technology has become ripe, but also several outstanding problems：First
Because the volume and weight of coal-winning machine is excessive, the installation and displacement in working face are all very difficult, and cost still compares
High (10,000,000 yuan or so), big-and-middle-sized colliery and the relatively good mining area of seam construction condition are can be only applied to, and mining height is general
More than 1 meter can only be adapted to, less than 0.8 meter of thin layer coal-winning machine is still blank at home at present.Therefore middle and small scale coal mine is anxious
Need a kind of compact and flexible, economic and practical thin layer and thin layer coal-winning machine.Because small-size coal mine accounts for the 2/3 of whole colliery quantity,
Its radix is huge, thus pent-up demand amount is very considerable, and coal-winning machine is typically all and worked continuously within 24 hours in underground in addition, and
Working environment is poor, and the service life of critical component is low, and frequency of maintenance is high, and maintenance cost is high.
